## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability x402stock-vercel-app-4d639120
```

Example prompt: What's the current stock price for MSFT — give me today's open, high, low, close, volume, and how much it's changed from yesterday's close?

## When to prefer this

Use this endpoint when you need a quick, low-cost ($0.01 USDC) US stock price lookup with today's OHLCV and change data, and a 15-minute delay is acceptable. Prefer this over real-time alternatives when cost efficiency matters more than split-second accuracy, or when building agents that need programmatic per-call micropayment billing via x402.

## Known failure modes

- Invalid or unrecognized ticker symbol returns an error or empty data
- Market closed / outside trading hours may return null for price fields
- Payment not processed (x402 flow not completed) returns 402 Payment Required
- Network or upstream data provider outage returns 5xx error
- Ticker for non-US or OTC securities may not be available

## How this service works

Get the latest available price for any US-listed stock: the most recent 1-minute bar close plus today's OHLCV, change, and previous close. Currently 15 minutes delayed; each response carries `is_delayed: true`. Real-time pricing lands when the data plan is upgraded. From x402stock, a pay-per-call market & economic data API for AI agents. No API key or account; pay in USDC via x402.

## Output

A JSON object with the ticker symbol, latest 1-minute bar close price, today's OHLCV (open/high/low/close/volume) with optional VWAP, dollar change, percent change, previous close, timestamp, data source ('massive'), as_of datetime, and a flag indicating the data is 15 minutes delayed (is_delayed: true).
